The X-37 for NASA was to be powered by one Aerojet AR2-3 engine using storable propellants, providing thrust of 6,600 pounds-force (29.4 kN). [50] The human-rated AR2-3 engine had been used on the dual-power NF-104A astronaut training vehicle and was given a new flight certification for use on the X-37 with hydrogen peroxide/ JP-8 propellants ...

A route's grade is provisional until enough climbers have repeated the route to have a "consensus". At the highest grades, this can take years as few climbers are capable of repeating these routes. For example, in 2001, Realization was considered the world's first 9a+ (5.15a), however, the first repeat of the 1996 route Open Air [ de ] , which ...
OTV-7 is the fourth mission for the second X-37B built, and the seventh X-37B mission overall. It was flown on a Falcon Heavy in the expendable center core-recoverable side cores configuration, and launched from Kennedy Space Center Launch Complex 39A.
Once Albert was able to free-climb the entire route, and avoid all the red "X"s, he would then paint a red "dot" (the "Roter Punkt") at the base of the route. His first Rotpunkt was the aid climbing route Adolf-Rott-Gedächtnis-Weg (V+/A1) at the Streitberger Schild crag in the Frankenjura, which he freed at 6a+ (5.10b) in 1975. [1]
The specifications were similar to the as-delivered X37-X44, but with upgraded braking equipment. The reasoning for the order was that, as well as traffic increases (now up to 13.5 million train miles per year), the earlier diesel-electric locomotives were coming due for major overhauls, with no spare motive power to fill the gaps in the ...
Odell Beckham Jr. opened up about his health and a recent diagnosis. The NFL star recently told Prevention he has a chronic skin condition, seborrheic dermatitis. “When I found out millions of ...
The X-38 is an experimental re-entry vehicle designed by NASA to research a possible emergency crew return vehicle (CRV) for the International Space Station (ISS). The 1995–2002 program also developed concepts for a crew return vehicle design that could be modified for other uses, such as a possible joint U.S. and international human spacecraft that could be launched on the French Ariane 5 ...
